Default Reference of charcoal cannister line needed!

This is on an EFI, 2.3L, 1991.

So on the driver side, down between the radiator and the fender cowl is a charcoal cannister. One side is a line from the fuel tank. The other side has pre-formed plastic tube and through all my contortions and tetris-like maneuvres, I can't figure out what it would hook to.

Could anyone tell me or post a photo for reference?

The vacuum diagram on mine shows that this connects into the throttle body. But my Hayne's book says that the valve cover vent also connects to the same (and only) port on the throttle body(this is how it came).

I've seen some Rangers where the valve cover vent connects into the air box, which would make sense if the diagram was true, but there's no way I can get this tube to connect to the throttle body port and my airbox has no unused ports.

This line on mine was duct-taped up into some wires and vacuum lines and looked like it was genuinely going some place. It was only yesterday I realized it was indeed going nowhere and I've been driving this truck over two years. -_-

Note: I've already cruised all the pictures of 2.3L EFI engines on this site, and sent messages to users in hopes they'll be able to tell me what I need to know!

Well, I ended up tearing the throttle body back off, as well as the fuel rail, and all the electrical connections in the area. Up underneath the intake manifold port for the PCV valve was another hidden port that goes to that charcoal canister (or maybe they're reversed, or maybe it doesn't matter). Figuring that out also solved the problem of where my vacuum leak was and now everything seems to be running hunky-dory.
